A Tutorial on Links between Cosmic String Theory and Superstring Theory
Mahbub Majumdar
Cosmic superstrings are introduced to non-experts. First D-branes and strings are discussed. Then we explain how tachyon condensation in the early universe may have produce…
Inflation from Tachyon Condensation, Large N Effects
Mahbub Majumdar, Anne-Christine Davis
Using only general properties of the tachyon potential we show that inflation may be generic when many branes and anti-branes become coincident. Inflation may occur because of: (1)…
D-brane Anti-brane Annihilation in an Expanding Universe
Mahbub Majumdar, Anne-Christine Davis
The time-varying density of D-branes and anti-D-branes in an expanding universe is calculated. The D-brane anti-brane annihilation rate is shown to be too small to compete with the…
Cosmological Creation of D-branes and anti-D-branes
Mahbub Majumdar, Anne-Christine Davis
We argue that the early universe may be described by an initial state of space-filling branes and anti-branes. At high temperature this system is stable. At low temperature tachyon…
Inflation in Supersymmetric Cosmic String Theories
A. C. Davis, M. Majumdar
We examine a non-Abelian SUSY gauge theory and a SUSY U(1) theory originally used to investigate the microphysics of cosmic strings in supersymmetric theories.…
